Question

A car complete a journey in 10 hours . He travels first half of the journey at the rate of 21 km/ hr and second half at the rate of 24 km/hr . find the total distance of journey​

Answer 1

Answer:

Here goes the solution!

Total time of journey = 10 hours

First half of journey = Second half of journey =10/2 =5 hour

Now, speed= distance travelled/time taken

Since we already know speed and time taken,we can put that equation like this

Distance = Speed × time taken

Since the journey has two halves with different speed,

Total distance = Distance travelled in first half + Distance travelled in second half

Total distance =(21 × 5) + (24× 5) = 105 + 120 =225kms
