Question

the speed of car is 40 km/h moved for 4 hours. calculate the distance traveled​

Answer 1

Explanation:

distance = speed × time

so

distance = 40 km /h ×4 h

distance = 160 km

Answer 2

Distance travelled = speed × time taken

Speed = 40km/hr = 40 × (5/18) m/sec

Time = 4 hrs = (4×60×60) sec

$distance \: = 40 \times \frac{5}{18} \times 4 \times 60 \times 60 \\ \\ = 200 \times \frac{2}{9} \times 3600 \\ \\ = 400 \times 400 \\ \\ = 160000m = 160km$
