Answer:

39.2 km/hr.

Step-by-step explanation:

Given,

Mariko distance to work = 72 mile

1 mile = 1.6 Km

72 mile = 1.6 x 72= 115.2 km

time taken to cover this distance = 2.25 hr

Average speed of mariko = 115.2/2.25 = 51.2 km/hr

Issei distance to work= 226 Km

time taken by issei = 2.5 hr

Average speed of issei = 226/2.5 = 90.4 Km/hr

Difference between their average speed

     = 90.4 - 51.2 = 39.2 km/hr

Hence, the average speed difference is equal to 39.2 km/hr.

PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!
Mamont248 [21]

Answer: x < -4 and -4 > x

x < -4 would be one of the two options.

This means that any number less than -4 is a solution.

This is shown by drawing an open dot on -4 and then

drawing an arrow to the left shows all answer less tan 4.

-4 > x would be our second option.

We can change it to say x < -4.

All I did was changed the order of numbers and switched the sign.

So x < -4 is the same as the first option.
