Answer 1

Answer:

0.118 seconds

Step-by-step explanation:

This is a distance-rate-time problem, so we need to use the formula: d = rt, where d is the distance, r is the rate, and t is the time.

Here, the distance is actually the height, which is $3.54*10^7$ metres. The rate is $3.00*10^8$ metres per second. Plug in these values to find t:

d = rt

$3.54*10^7$ = $3.00*10^8$ * t

Divide both sides by $3.00*10^8$:

t = 0.118 seconds

The answer is 0.118 seconds.

Answer 2

Answer:

0.118 seconds

Step-by-step explanation:

Speed = distance/time

3 × 10⁸ = (3.54 × 10⁷)/time

1/time = (3 × 10⁸)/(3.54 × 10⁷)

1/time = (30 × 10⁷)/(3.54 × 10⁷)

1/time = 8.474576271

time = 1/8.474576271

time = 59/500 = 0.118 seconds
