Question

the speedometer of a bike reads 52 km/h at 8.00 hours and after travelling for a certain distance ,it reads 66 km/h at 8.25 hours. find the distance travelled by this time period.

Answer 1

Distance traveled = Average speed × Time

Average speed = $\frac{52 + 66}{2}$
                       
                          =  59 km/hr

Time duration = 8.00 - 8.25
                       = 25 min 
                       = $\frac{25}{60} hours$

So ,

       Distance traveled = 59 ×  $\frac{25}{60}$
               
                                    = 24.58 kilometers. 

Answer 2

Answer:

hope it will helpful to you

... answer given below .

Explanation:

Distance traveled = Average speed × Time

Average speed = \frac{52 + 66}{2}

2

52+6

= 59 km/hr

Time duration = 8.00 - 8.25

= 25 min

= \frac{25}{60} hours

60

25 hours

So ,

Distance traveled = 59 × \frac{25}{60}

60

25 = 24.58 kilometers

hence it solved.
