Question

The longest time a man could spend on the moon is approximately 3.124769 days. How long is this in (a) hours and (b) minutes?

Answer 1

(a) 74.994456 hours

(b) 4499.66736 minutes

Step-by-step explanation:

We remind ourselves that

1 day = 24 hours

1 hour = 60 minutes

Therefore,

1 day = 24 x 60 = 1440 minutes

Part (a).

Therefore, to convert 3.124769 days into minutes, we do the following.

`3.124769\;days*24\;hrs/day`
`=74.994456\;hrs`

Part (b).

To convert days to minutes we realize that 1 day = 1440 minutes; therefore,

`3.124769\;days=3.124769\;days*1440\min`
`=4499.66736\;\;\min`

Hence, to summerise

(a) 74.994456 hours

(b) 4499.66736 minutes
