Answer:
The distance travel by cyclist in 20 seconds is 528 feet .
Step-by-step explanation:
Given as :
The speed of cyclist riding bike = s = 18 miles per hour
Let The distance cover by cyclist in 20 seconds = d feet per sec
<u>Now, According to question</u>
∵ 1 miles = 5280 feet
∴ 18 miles = 5280 × 18 = 95,040 feet
So, The speed of cyclist in feet per hour = 95,040 feet per hour
<u>Again,</u>
∵ 1 hours = 3600 seconds
So, The speed of cyclist in feet per sec = ft/sec
∴ The speed of cyclist in feet per sec = 26.4 feet per second
<u>Again</u>
∵ In 1 sec the distance cover by cyclist = 26.4 feet
∴ In 20 sec the distance cover by cyclist = 26.4 × 20 feet
i.e In 20 sec the distance cover by cyclist = 528 feet
Hence, The distance travel by cyclist in 20 seconds is 528 feet . Answer
Answer:
a) The Total fee, that Mike charges for 4 hours of instruction is $152
b) The total fee, that Tony charges for 4 hours of instruction is $148
c) The difference between total fee Mike and Tony charge for 4 hours of instructions is $4
Step-by-step explanation:
a) What is the total fee, that mike charges for 4 hours of instruction.
Mike charges $12 for travel expenses and $35 per hour for instruction.
So, the equation will be: where h is number of hours and y is cost
Put h=4 and find cost
So, the Total fee, that Mike charges for 4 hours of instruction is $152
b) What is the total fee, that Tony charges for 4 hours of instruction
Tony's fee can be modelled by C=32h+20 where h is number of hours and C is cost
Put h=4
So, the total fee, that Tony charges for 4 hours of instruction is $148
c) What is the difference between total fee Mike and Tony charge for 4 hours of instructions.
Cost for Mike = $152
Cost for Tony = $148
Difference = 152 - 148 = 4
So, the difference between total fee Mike and Tony charge for 4 hours of instructions is $4
