Question

A car takes 10hours to cover a certain distance at a speed of 40km/hr .find the time taken if its speed is increased by 10km/hr​

Answer 1

Distance = Speed * Time

= 40 * 10 = 400km

Speed increased = 40 + 10 = 50km/h

Time = Distance / Speed

= 400 / 50

= 8h

Time taken by increasing speed is 8 hours.

Answer 2

$\huge\bold\red{ANSWER:-}$

LET ASSUME A car takes 10hours to cover a certain distance at a speed of 40km/hr.

.'. speed=distance/time

.'. distance =speed×time

distance =40×10

.`. distance =400km.

increasing speed =40+10=50km/hr.

AGAIN,

TIME =DISTANCE /SPEED

TIME=400Km/50km/hr

.'.time =8hrs.
