Changes speed
Passes through the boundary
Her acceleration is zero, because her velocity is not changing.
The total distance travelled is 307.5 miles.
<h3>What is the distance covered?</h3>
We know that the distance covered can be obtained from the formula from speed since the motion all took place in the same direction.
Speed = distance/time
distance = speed * time
In the first case;
Distance = 35 mph * 2.5 hours = 87.5 miles
In the second case;
Distance = 55 mph * 4.0 hours = 220 miles
Total distance = 87.5 miles + 220 miles = 307.5 miles
Hence the total distance travelled is 307.5 miles.
