Question

3. A man goes from his home to the grocery
shop at a speed of 6 km/h and returns at
a speed of 9 km/h. If the distance from his home to the shop is 900m calculate the total time that he spends travelling from his home to the shop and back

Answer 1

Answer:

Total time taken is 14.4 min

Step-by-step explanation:

d = 900 m = 0.9 km, s1 = 6 km/h

1. Time = Distance / speed
2. Time = 0.9 / 6 h
3. Time = 0.15 h

d = 0.9 km, s2 = 9 km / h

1. Time = Distance / Speed
2. Time = 0.9 / 9 h
3. Time = 0.09 h

Total Time taken = 0.15 h + 0.09 h

= 0.24 h

= 14.4 min
