A toy rocket is lunch vertically upward from ground level in into velocity of one 28 ft./s how long will it take for the rocket

pentagon [3]

Answer:

1.14 s

Step-by-step explanation:

Time, $t=\frac {d}{s}$

Here, d is the distance and s is the speed/velocity

Since we're given the velocity, s as 28 ft/s and the distance between the position of the rocket and ground as 32 ft then

$t=\frac {32}{28}=1.142857143\approx 1.14 s$

Therefore, it needs 1.14 seconds

Vaselesa [24]

12:45Answer:

Part A: 9 hours 45 minutes

Part B: $126.1575

Step-by-step explanation:

Part A,

From 7:45 to 12:15 is 4 hours and 30 minutes

From 12:45 which he clocked back in to 6:00 is 5 hours and 15 minutes.

4 hours and 30 minutes plus 5 hours and 15 minutes = 9 hours and 45 minutes.

Part B, 9 hours and 45 minutes can be represented as 9.45

And since he gets 15.35 "per" hour shows we can multiply.

15.35 x 9.45 = 126.1575

Therefor he earned 126.15.
