Traveling at a speed of 50 kilometers per hour, how far does the car move in 3.5 hours? *

175 kilometers

Explanation:

50 × 3.5 = 175

or

50 x 3 = 150 +

50 x 0.5 = 25

150 + 25 = 175 kilometers

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h
