Reggie ran 44 yards in 4.4 seconds. What was his speed? ​

he formula which relates distance, speed, and time is:

d = rt, where d is the distance traveled, r is the rate of travel or speed, and t is the time traveled.

Since we're given that r = 60 km./hr. and time t = 2 hrs. 20 min., then we can find time d traveled by the bus by substituting the given information into the distance-speed-time formula as follows:

d = rt

d = (60 km./hr.)(2 hrs. 20 min.)

= (60 km./hr.)(2⅓ hrs.)

NOTE: 20 minute = ⅓ of an hour.

= (60)(7/3) km.

NOTE: 2⅓ = 7/3

= (60/3)(7) km.

= (20)(7) km.

d = 140 km. is the distance a bus traveling at 60 km./hr. can travel in 2 hrs. and 20 min.

the  frequency of a wave represents  the number of wavelengths that pass a specific point per second. the unit for  frequency  is hertz (hz).

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.
