To round 978 to the nearest ten, you would look at the digit in the tens place, which is 7. Since 7 is greater than or equal to 5, you would round up to the next ten, making it 980. **

A parking brake, also known as a handbrake or emergency brake, is a secondary braking system in a vehicle that is used to prevent the vehicle from moving when parked. It is typically a lever or pedal that when engaged, applies the brakes to the rear wheels only, helping to keep the vehicle stationary. The parking brake is separate from the main braking system and is often used in conjunction with the transmission's park position to provide extra security when parked on a slope or for extended periods of time. **

The parking brake, also known as the handbrake or emergency brake, is a secondary braking system in a vehicle that is used to prevent the vehicle from moving when parked. It is typically a lever or pedal that, when engaged, applies the brakes to the rear wheels, holding the vehicle in place. The parking brake is especially useful when parking on a slope or when the vehicle is stationary for an extended period of time. It is important to use the parking brake in addition to the regular brakes to ensure the vehicle remains secure. **

The choice between a handbrake and an electronic parking brake ultimately comes down to personal preference and the specific features of the vehicle. Handbrakes are traditional and offer a tactile feel, while electronic parking brakes are often more convenient and can offer additional safety features such as automatic engagement. Some drivers may prefer the simplicity of a handbrake, while others may appreciate the modern technology and ease of use of an electronic parking brake. Ultimately, both options can effectively secure a parked vehicle, so it's a matter of individual preference. **
