Answer:
A covered greater distance.
Explanation:
The distance travelled will be the area under the slope.
the distance travelled by A=area of the trapezium
The distance travelled by B=area of the right angled triangle.
distance travelled by A= 375m.(area of triangle +area of rectangle => 125+250)
distance travelled by B= 125m(area of the triangle=1/2bh =125)
difference= 375-125=250m
Hope it helps!
