An ant crawls 10 cm in 4 seconds. How far can the ant crawl in 5 seconds?

Answer 1

Set up a proportion

10 cm / 4 sec = ? / 5 sec

cross multiply

50 / 4 = 12.5 cm

Answer 2

10 = 4

x 5

10*5=50 and x*4= 4x

50/4=12.5

Answer 3

If the ant can crawl 10 cm in 4 seconds, we need the number of cm per second.

10cm / 4sec = 2.5 cm per second.

Now we need to multiply the cm per second times the number of seconds, that being 5.

2.5 cm/s x 5s = 12.5cm.

Your answer is 12.5 centimeters.

Answer 4

10 cm/ 4 sec = ? / 5 cm

cross multiplies

10*5 = 4*?

50 = 4* ?

?=50/4 = 25/2 = 12 + 1/2
