The weight is 45 N, because the three chains hold the sign, and each contributes 15 N.

Notice that the mass would be the weight/acceleration of gravity, m = 45/9.8 kg. But they ask the weight (force, so Newtons)

A car travels 98 miles in 1 hour and 45 minutes. what is the average speed?
Greeley [361]
Firstly let us get the time down to minutes from hours. Then the calculation will become easy.
1 hour and 45 minutes = (60 + 45) minutes
                                     = 105 minutes
So
The distance traveled by the car in 105 minutes = 98 miles
Then
The distance traveled by the car in 60 minutes = (98/105) * 60 miles
                                                                           = 5880/105 miles
                                                                           = 56 miles
So the average speed of the car as can be seen from the above deduction is 56 miles per hour.
