Can someone help me solve this?

2.828

Step-by-step explanation:

Pythagoras theorem (a^2)+(b^2)=(c^2)

also written as (base^2)+(altitude^2)=(hypotenuse^2)

Base=2

altitude=2

=Base = 2*2=4

=Altitude = 2*2=4

4+4

=8

√8

=2.828

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
