Answer:
The Answer is both B and C, since it has same options from the question given. Gear, slow her vehicle in a lower
Explanation:
The use of a lower gear in a vehicle helps a person to control their speed limits, when approaching a hill. it also saves the brakes too, using the brakes down a hill can overheat the gear and causes brake failures
By changing in into a lower gear and also letting the engine to do the brake work in a vehicle, the engine will absorb a force and slow the vehicle down, but in most cases brakes can be applied but with lesser pressure.
In this case Stella need to slow down by applying her lower gear down a hill to avoid accidents on the road, by controlling her speed limits and for safety precaution
Answer:
b. gear, slow her vehicle in a lower
c.
Explanation:
When driving downhill, use a lower gear so as to increase the effect of engine braking and reduce the risk of overheating the brakes.
By using a low gear while driving, the engine should rev higher than usual as this is part of the engine braking system.
It helps tackle steep drops because applying too much pressure on your car’s brakes could cause them to fail.
