Lesson: Ratios and Rates

Comment on Ratios and Rates

How do I know when to use ratios and when to use the speed-distance-time formulas?

You can use ratios for simpler motion if/when you're able to rewrite the information as "for every x there is y" (as mentioned in the video)

Will we have calculators for these type of questions?

Unfortunately no.

No calculators are permitted during the Math section of the GMAT.
