Question

car travel at 90 km/hr in speed. how much distance cover in 8 sec​

Answer 1

Step-by-step explanation:

speed = 90km/h

convert it in SI unit

90/3.6 = 900/36 = 25 m /s

time = 8 sec

we know that

speed = distance / time

distance = speed x time

d = 25 x 8

d = 200 m. Ans

Answer 2

Answer:

QUESTION:

Car travel at 90 km/hr in speed. how much distance cover in 8 sec .

GIVEN:

$Speed = 90 km/hr$

$Time = 8 sec$

TO FIND:

$Distance = ??$

CONCEPT:

FIRST MAKE 90 KM/HR INTO M/SEC .

THEN MULTIPLY M/SEC × 8 SEC

FORMULAS:

$km \: per \: hr \: into \: m \: per \: sec$

$= \: \frac{8}{15} \times km \: per \: hr \: = m \: per \: sec$

$distance \: = \: speed \: \times \: time$

SOLUTION:

$\frac{8}{15} \times 90$

$8 \times 6 = 48 \: m \: per \: sec$

NOW ,

$48 \times 8 \: = \: distance$

$384 \: m \: in \: 8 \: second$
