If i pedal at a rate of 16 miles per hour, how long will it take me to ride 12 miles.
Elan Coil [88]

Answer:

45 minutes

Step-by-step explanation:

16 and 12 have the GCF of 4, so you divide both by 4. Then, since you know one hour is 60 minutes, you divide that by 4 as well to get a base unit of 15 minutes per 4 miles. Then, just take the number you got from dividing 4 by 12 (3) and multiply it by 15 to get 45 minutes.

If one costs £0.05, find the cost of 100
Rina8888 [55]
This is quite simple once you understand.
Since 100 is a round number all you must do is move the 0.05 up 2 zeros.
You get the zeros from the hundreds btw. 

0.05 x 100 = 5
So the answer is £5
