Question

the formula relating distance, speed and time is d = st. depending on their positions in orbit, the distance from earth to mars varies from a minimum of 56 000 000 km to a maximum of 402 000 000 km. a space probe travels 28 000 km/h. the average distance between earth and mars is 150 000 000 km. how long does it take the probe to travel from earth to mars, on average?

Explanation:

Step1: Identify given values

We know $d = 150000000$ km (average distance) and $s=28000$ km/h (speed). The formula is $d = st$, and we need to find $t$.

Step2: Rearrange the formula for $t$

From $d = st$, we get $t=\frac{d}{s}$.

Step3: Substitute values

$t=\frac{150000000}{28000}\text{ h}$.

Step4: Calculate the result

$t=\frac{150000000}{28000}=\frac{150000}{28}=\frac{37500}{7}\approx5357.14$ h.

Answer:

$\frac{37500}{7}\text{ h}\approx5357.14$ h
