Question

The odometer of a car reads
2000 km at the start of a trip and
2400 km at the end of the trip. If the
trip took 8 h, calculate the average
speed of the car in km/h' and m/s.​

Answer 1

Answer:

50 km in km/h And 13.889 in m/s

Explanation:

First subtract 2000 from 2400 then divide it by 8. Then you get 50 k/mh then convert it into m/s(meter per second)

Answer 2

Find-Average speed =?

$\underline{ \large \purple{ \mathscr{\dag\:G \bf{iven}=}}}$

Initial reading=2000km

Final reading=2400km

Time= 8h

Formula to be used :

$\boxed{Average \ speed= \dfrac{Total \ Distance}{Total\ time}}$

$\underline{ \large \red{ \mathscr{\dag\:S \bf{olution}=}}}$

Average speed in Km/hr:

=>Average speed=2400-2000/8

                           =50 km/hr

Average Speed in m/s:

50km/hr=50x5/18

            =250/18

            =13.88m/s

$\therefore\:\underline{\textsf{Average speed is \textbf{13.88m/s}}}.$
