Question

If a boat travels 4km in 1 hour how much time a boat will take to cover in 10Km

Answer 1

Time taken by the boat to cover 4 km = 1 hr
Time taken by the boat to cover 1 km = 1/4 hr
Time taken by the boat to cover 10 km = 10×1/4
=5/2hr or 2.5hr
Ans:- 5/2 hr or 2.5hr which is 2 hr 30 min

Answer 2

distance travelled by boat in 1 h = 4km

distance it will cover in 1/2 h

= 4 /2 = 2km

distance it will cover in 2h = 2×4 = 8km

now time taken by boat to cover distance of 10km = 2 h+ 1/ 2h

( 4+ 1 ) h/ 2

= 5 / 2

= 2.5 h

= 2hour 30 minutes

hence, it will take 2hour 30 minutes to cover the distance of 10 km.
