speed of boat = 20km/4 hrs
= 5km/h
distance covered in 7 hrs = speed × time
= 5km/h × 7hrs
= 35 km.
= 5km/h
distance covered in 7 hrs = speed × time
= 5km/h × 7hrs
= 35 km.

Distance travelled in 4 hrs = 20 km
Distance travelled in 1 hr = 20/4 = 5 km
Distance travelled in 7 hrs = 5 x 7 = 35 km
Distance travelled in 1 hr = 20/4 = 5 km
Distance travelled in 7 hrs = 5 x 7 = 35 km
