Question

a man completes a journey in 10 hours he travels first half of the journey at the rate of 21 kilometre per hour and second half at the rate of 24 km per hour find the total journey in kilometre​

Answer 1

Answer:

The answer is 225 km.

Step-by-step explanation:

Speed the man travels in the first half of the journey- 21 km/h

As he travelled for 10 hours so the half of 10 will be 10÷2=5

Distance he travelled in the first half of the journey- (5×21)= 105km

Speed the man travels in the second half of the journey- 24 km/h

Distance he travelled in the second half of the journey- (5×24)= 120km

Total distance travelled by him- distance travelled in first half+distance travelled in second half

=(105+120)km

=225 km

The man traveled 225 km in total.
