Answer:
1. w = nr
2. His wage is £52.00
Step-by-step explanation:
1. Given that wages is a function of number of hours worked multiplied by hourly rate
Where n represents hours and r represents rate.
Wage formula is as follows;
Wage (w) = hours (n) * rate (r)
w = n * r
w = nr
2. If he worked 5 hours at a rate of £10.40 per hour
This means
n = 5
r = 10.40
His wage is as follows;
w = nr
w = 5 * £10.40
w = £52.00
Hence, his wage is £52.00

Answer:
They biked for 1 hour and 38 minutes
Step-by-step explanation:
Here, we want to know the length of the biking time
Mathematically, from the time given;
if they had ended the biking by 2:47
They would have biked for 2 hours
But, as it can be seen, the biking stopped at 2:25 and that is (57-25 = 22 minutes earlier)
So, the length of their biking time would be;
1 hour and (60-22) minutes
and that is 1 hour 38 minutes
V = S*h
h = V/S = 250*pi / 50*pi = 5 m
