Answer :
(-3.7 meter/second) - (13.9 meter/second) = -17.6 meter/second
(21.4 second) - (72 second) = -50.6 second
Explanation :
(1) As we are given the expression :
(-3.7 meter/second) - (13.9 meter/second)
Now we have to evaluate this expression, we get:
⇒ -17.6 meter/second
(2) As we are given the expression :
(21.4 second) - (72 second)
Now we have to evaluate this expression, we get:
⇒ -50.6 second
