15 : kerri drives $150$ miles to visit her grandmother. she starts off driving $60$ miles per hour, but then encounters road construction and has to drive $20$ miles per hour the rest of the way. if she spends the same amount of time at the faster speed as at the slower speed, then how many hours did her $150$-mile trip take in total?

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
